NIKE AIR MAX 270 REACT. * Nike React technology creates a lightweight, durable foam for a smooth, responsive ride. * Max Air unit provides high-rebound cushioning. * Lightweight, no-sew layered materials create a modern style and aesthetic. * Soft, minimal collar comfortably fits around the heel. I've worn these about 3 times and stored them at home. Please check the photos for the condition before making a purchase. Thank you very much.
